"They just made some good swings," Laird said. "Rizzo went out and got that ball, hit it down the line. Dioner hit that slider down and in. You've got to tip your cap to them."
Medlen held Chicago to one run and six hits in 7 1/3 innings after going 4-0 with an 0.98 ERA in his previous four starts.
"It's tough, but I'm a former bullpen guy, and I know how tough that job is," Medlen said. "The dudes do their best. They've carried us the entire year, so these things happen and nobody in this clubhouse is panicking at all or anything. Credit their pitcher with keeping the game close, too. (Travis) Wood's having a great year. I felt it all game. I felt like it was in my hands, and the game was over. I had all the confidence in the world in myself and I just tried making pitches."
Pedro Strop struck out the side in the ninth for his first save in four chances.
Atlanta went ahead in the fourth when Freeman walked and scored on Gattis' single. But B.J. Upton also struck out looking with the bases loaded to end the rally.
Wood settled down after that, allowing one run, five hits and four walks in seven innings with seven strikeouts.
"I had pretty command of most my pitches, being able to locate my fastball and getting the cutter on their hands and get some early swings and some quick outs," Wood said. "Just that last inning kind of got away from me quick. I really wanted to go out there and finish it strong and maybe overtried a little bit and left a pitch over that Upton could hit and Freeman battled me."
